Letters Patent No. 68,000, dated August20,'1867 l'IMPROVEMENI' IN GHUR-DASHER;

TO ALL WHOM'IT MAY VGONCERNV:

Be it known that I, J. W. PETTENGILL, of Rockford, in the county of Winnebago, and-State of Illinois, have invented a new and improved Dasher4 for Churns; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had tothe accompanying drawings, forming part of this specification.

The present invention relates to a dasher for churns 4more particularly, which in its construction in fact embraces two in one, it working4 to crush or mash the cream without a rubbing' or'grinding movement, which, as

is well known, has a tendency to leave the butter soft and salvey, 'while ifmashed or crushed it is rendered hard and brittle. -In the accompanying plate of drawingsmy improved dasher for churns, die., is illustrated- Figure 1 being a side-elevation of the same.

Figure 2, Ia. plan or top View of one section of` plate thereto, and

Figure 3 a partial vertical section. Y

Similar letters ofreference indicate corresponding parts.

A, in the drawings, represents the shaft or spindle to the dasher. Thisshaft A, at oneend, has a crosshandle, B, and at the other has secured to it a circular plate or disk, C, in and through which is turbe made a. series of'holes, such as are shown in iig. 2. Above thisdisk C, on the stem, is securedanother similarly perfo- :ratcd disk, D, b'etween which and the lower one, C, on the spindle, is arranged to play or move a perforated disk, E, the' perforations in the several'plates being so located. as not to be opposite to or in corresponding positions with each other. F, acentrc-piecc iixed to shaft A above its upperdisk. D. This piece F is made flat upon its two pieces Gr, and to cachof such faces a similar right-angular wir g, H, is hinged at -its angleI. These wings- H through both of 'their sides J are perforated.

In the operation of the dasher, above described, as it is forced down through'the cream, the cream rushes or passes through the holes in the lower/disk or plate C, driving the loose intermediate disk E up against the upper diskPD, becauseof the holes in each disk being so located as not to correspond in position. At the` same time the wings at the upper centre-.pieccG are brought forcibly against the same above the joint', and tcewersa, as the dasher is raised.'

The effect of the above operation of thedas'her is to break up theglobules of crearucontaining the butter,

and to gather or collect the butter immediately.

I claim as new, and desireto secure by Letters Patent- A dashcr for churns, Sac., consisting of three ormore perforated disks or plates C, I), and E, arranged4 together substantially as and for the purpose described I also 'claim thc cen V'ie-piece to the stem or `handle, carrying angular perforated wings, substantially as and for thepurposedescrihed, and whether used in combination with'the'three or more disks to such stem or not.
